Question

решите уравнение 3,5х+2,2хравно4,56
3,2у-2,7у равно 0,6
3,7z-z равно0,54

Answer 1

3.5х+2.2х=4.56
5.7х=4.56
х=4.56:5.7
х=0.8
3.2у-2.7у=0.6
0.5у=0.6
у=0.6:0.5
у=1.2
3.7z-z=0.54
2.7z=0.54
z=0.54:2.7
z=0.2

Answer 2

$3.5x+2.2x=4.56;5.7x=4.56;x=4.56/5.7=0.8;$
$3.2y-2.7y=0.6;0.5y=0.6;y=0.6/0.5;y=1.2;$
$3.7z-z=0.54;2.7z=0.54;z=0.54/2.7;z=0.2$
